  • Any way to make DataContractJsonSerializer serialize Dictionaries properly?

    - by morpheus
    The DataContractJsonSerializer is not able to serialize Dictionaries properly. Whereas JavaScriptSerializer serializes Dictionaries as {"abc":"xyz","def":42} for example, the DataContractJsonSerializer gives [{"Key":"abc","Value":"xyz"},{"Key":"def","Value":42}] instead. This is really problematic and I want to know how can I serialize Dictionary objects correctly in my WCF service. I am looking for a solution that would require least amount of effort. ref: http://msdn.microsoft.com/en-us/library/bb412170.aspx

  • How do I encode Unicode strings using pyodbc to save to a SAS dataset?

    - by Chris B.
    I'm using Python to read and write SAS datasets, using pyodbc and the SAS ODBC drivers. I can load the data perfectly well, but when I save the data, using something like: cursor.execute('insert into dataset.test VALUES (?)', u'testing') ... I get a pyodbc.Error: ('HY004', '[HY004] [Microsoft][ODBC Driver Manager] SQL data type out of range (0) (SQLBindParameter)') error. The problem seems to be the fact I'm passing a unicode string; what do I need to do to handle this?

  • C# Windows Service Multiple Config Files

    - by Goober
    Quick Question Is it possible to have more than 1 config file in a windows service? Or is there some way I can merge them at run time? Scenario Currently I have two config files containing the below contents. After I build and install my Windows Service, I can't get my custom XML Parser class to read the content because it keeps pointing to the wrong config file, even though I am using a few lines of code to ensure it gets the right name of the config file I need to access. ALSO When I navigate to the folder in which the service is installed, there is only sign of the normal APP.Config file, and no sign of the custom config file. (I have even set the normal ones properties to "Do Not Copy" and the custom ones properties to "Copy Always"). Config File Determination Code string settingsFile = String.Format("{0}.exe.config", System.AppDomain.CurrentDomain.BaseDirectory + Assembly.GetExecutingAssembly().GetName().Name); CUSTOM CONFIG File <?xml version="1.0" encoding="utf-8" ?> <configuration> <servers> <SV066930> <add name="Name" value = "SV066930" /> <processes> <SimonTest1> <add name="ProcessName" value="notepad.exe" /> <add name="CommandLine" value="C:\\WINDOWS\\system32\\notepad.exe C:\\WINDOWS\\Profiles\\TA2TOF1\\Desktop\\SimonTest1.txt" /> </SimonTest1> </processes> </SV066930> </servers> </configuration> NORMAL APP.CONFIG File <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxx" /> </configSections> <connectionStrings> <add name="DB" connectionString="Data Source=etc......" /> </connectionStrings> </configuration>

  • Good way to create PDF from Office documents in Java

    - by Sindri Traustason
    I'm looking for a good way to convert Office (mostly Microsoft) documents to PDF in Java. I've been looking at using the OpenOffice SDK but from the samples I've looked at it looks like this requires having OpenOffice running in server mode to do the work. Does anyone know of a good way to do this? Good meaning the less external requirements, the better. A 100% Java API would be best, but I don't expect that actually exists.

  • What's special about mouse capture and middle mouse button in WPF?

    - by Scott Bilas
    When I call CaptureMouse() in response to a MouseDown from the middle mouse button, it will capture and then release the mouse. Huh? I've tried using Preview events, setting Handled=true, doesn't make a difference. Am I not understanding mouse capture in WPF? Here's some minimal sample code that reproduces the problem. // TestListBox.cs using System.Diagnostics; using System.Windows.Controls; namespace Local { public class TestListBox : ListBox { public TestListBox() { MouseDown += (_, e) => { Debug.WriteLine("+MouseDown"); Debug.WriteLine(" Capture: " + CaptureMouse()); Debug.WriteLine("-MouseDown"); }; MouseUp += (_, e) => { Debug.WriteLine("+MouseUp"); ReleaseMouseCapture(); Debug.WriteLine("-MouseUp"); }; GotMouseCapture += (_, e) => Debug.WriteLine("GotMouseCapture"); LostMouseCapture += (_, e) => Debug.WriteLine("LostMouseCapture"); } } } Generating a default WPF app that has this for its main window will use the test class: <Window x:Class="Local.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:Local" Title="MainWindow" Height="350" Width="525"> <local:TestListBox> <ListBoxItem>1</ListBoxItem> <ListBoxItem>2</ListBoxItem> <ListBoxItem>3</ListBoxItem> <ListBoxItem>4</ListBoxItem> </local:TestListBox> </Window> Upon clicking the middle button down, I get this output: +MouseDown GotMouseCapture LostMouseCapture Capture: True -MouseDown So I'm calling CaptureMouse, which in turn grabs and then releases capture, yet returns true that capture was successfully acquired. What's going on here? Is it possible that this is something with my Logitech mouse driver doing something goofy, trying to initiate 'ultrascroll' or something?

  • Save All Values of Database to Text File?

    - by cam
    I was wondering if there was a way to extract all the values of a column, and then save each value into separate text files (labeled ANYTHING, 1-100 works fine). I know how to do this through another language, but I'm using SQL Server 2008 with Microsoft SQL Server Manager and it would save me some time from figuring out how to do it through C#.

  • Are there free, low cost, or open source tools for matching name/address data?

    - by luiscolorado
    This question is related to Tools for matching name/address data. There is a number commercial tools provided by SAS, Oracle, Microsoft, etc., that allow to de-duplicate or merging names of individuals or companies coming from multiple sources. However, after reading the answers to the question mentioned before, I wondered why a seemingly interesting problem didn't receive any answers mentioning open source projects that could tackle the problem. Are you aware of any open source projects or algorithms to implement the so called "record linking", "record merging", or "clustering"?

  • How to sign XML document or verify XML document signature with C++?

    - by Budda
    Subj. I need to sign/verify in native C++ (no .NET), using private key for signing, public key for verification. I saw few examples on MSDN (http://msdn.microsoft.com/en-us/library/ms761363(VS.85).aspx) that demonstrate how to sign the document with CSP (I don't know what this means). For my case I need to create a "key" from the binary data array... can somebody help me with that? Thank you in advance.

  • Can I use reflection to find the bin/[Configuration] folder in ASP.NET instead of the asp temporary

    - by vfilby
    I have an ASP.NET website and I want to find the /bin/[Configuration] folder to use an external tool. When I use reflection to get calling assemblies location it returns something similar to: C:\Windows\Microsoft.NET\Framework\...\Temporary ASP.NET Files\a1388a5e\...\my.dll Since each dll has its own directory under the temp ASP.NET Files this fails for me. How can I get the location of the binary, not asp.net's temporary cache?

  • Issues querying Access '07 database in C#

    - by Kye
    I'm doing a .NET unit as part of my studies. I've only just started, with a lecturer that as kinda failed to give me the most solid foundation with .NET, so excuse the noobishness. I'm making a pretty simple and generic database-driven application. I'm using C# and I'm accessing a Microsoft Access 2007 database. I've put the database-ish stuff in its own class with the methods just spitting out OleDbDataAdapters that I use for committing. I feed any methods which preform a query a DataSet object from the main program, which is where I'm keeping the data (multiple tables in the db). I've made a very generic private method that I use to perform SQL SELECT queries and have some public methods wrapping that method to get products, orders.etc (it's a generic retail database). The generic method uses a separate Connect method to actually make the connection, and it is as follows: private static OleDbConnection Connect() { OleDbConnection conn = new OleDbConnection( @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:\Temp\db.accdb"); return conn; } The generic method is as follows: private static OleDbDataAdapter GenericSelectQuery( DataSet ds, string namedTable, String selectString) { OleDbCommand oleCommand = new OleDbCommand(); OleDbConnection conn = Connect(); oleCommand.CommandText = selectString; oleCommand.Connection = conn; oleCommand.CommandType = CommandType.Text; OleDbDataAdapter adapter = new OleDbDataAdapter(); adapter.SelectCommand = oleCommand; adapter.MissingSchemaAction = MissingSchemaAction.AddWithKey; adapter.Fill(ds, namedTable); return adapter; } The wrapper methods just pass along the DataSet that they received from the main program, the namedtable string is the name of the table in the dataset, and you pass in the query you wish to make. It doesn't matter which query I give it (even something simple like SELECT * FROM TableName) I still get thrown an OleDbException, stating that there was en error with the FROM clause of the query. I've just resorted to building the queries with Access, but there's still no use. Obviously there's something wrong with my code, which wouldn't actually surprise me. Here are some wrapper methods I'm using. public static OleDbDataAdapter GetOrderLines(DataSet ds) { OleDbDataAdapter adapter = GenericSelectQuery( ds, "orderlines", "SELECT OrderLine.* FROM OrderLine;"); return adapter; } They all look the same, it's just the SQL that changes.

  • SSRS Parameters Displaying incorrectly

    - by Ryan
    Basically, I have a datetime parameter, after picking a date with the calendar widget, the date will display correctly (12/1/2010 or 1-DEC-2010). If the parameter tab refreshes in any way, either from report processing or changing another of the parameters, the date flips the month and day (1-DEC-2010 becomes 12-Jan-2010, or 12/1/2010 becomes 1/12/2010). I'm utilizing the SSRS plugin for C# (Microsoft.Reporting.Winforms.ReportViewer). Has anyone seen anything like this?

  • Prevent <xsi:nil="true"> on Nullable Value Types when Serializing to XML.

    - by Nat Ryall
    I have added some nullable value types to my serializable class. I perform a serialization using XmlSerializer but when the value is set to null, I get an empty node with xsi:nil="true". This is the correct behaviour as I have found here: http://msdn.microsoft.com/en-us/library/ybce7f69%28VS.80%29.aspx Is there a way to switch off this option so that nothing is output when the value type is null?

  • Should I use ICommand or Expression.Interactions InvokeCommand for MVVM in Silverlight 4?

    - by phejndorf
    I'm about to embark on a new project in Silverlight 4, and definitely want to take advantage of the MVVM pattern, now I've finally grasped the basics. For implementing commands in Silverlight 4 it seems there are rather a lot of options ranging from the new built-in Command/ICommand option on the Button, over the InvokeCommand defined in the Microsoft.Expressions.Interactivity namespace and on to the range of assisting MVVM frameworks (Prism, MVVMlight etc). Does anyone here have gotcha's, experience and wisdom to share on this subject?

  • Biztalk - how do I set up MSMQ load balancing and high availability ?

    - by FullOfQuestions
    Hi, From what I understand, in order to achieve MSMQ load-balancing, one must use a technology such as NLB. And in order to achieve MSMQ high-availability, one must cluster the related Biztalk Host (and hence the underlying servers have to be in a cluster themselves). Yet, according to Microsoft Documentation, NLB and FailOver Clustering technologies are not compatible. See this link for reference: http://support.microsoft.com/kb/235305 Can anyone PLEASE explain to me how MSMQ load-balancing and high-availability can be achieved? thank you in advance, M

Here for testing i wl build the application in Windows XP OS and copy the exe in to system containg the Windowsserver 2008 machine and replace it So what i did is i added a manifest like this name of that is myproject.exe.manifest My project has 3 folders like Headerfile,Resourcefile and Source file.I added this manifest(myproject.exe.manifest) in the Sourcefile folder containing other cpp and c code <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="4.0" processorArchitecture="X7460" name="myproject" type="win32"/> <description>myproject Problem</description> <!-- Identify the application security requirements. --> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> <security> <requestedPrivileges> <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/> </requestedPrivileges> </security> </trustInfo> </assembly> then i added this line of code in Resourcefile(.rc).Means one header file is there(Myproject.h).I added the line of code there #define MANIFEST_RESOURCE_ID 1 MANIFEST_RESOURCE_ID RT_MANIFEST "myproject.exe.manifest" Finally i did the following step Under Project, select Properties. 3. In Properties, select Manifest Tool, and then select Input and Output. 4. Add in the name of your application manifest file under Additional manifest files. 5. Rebuild your application. But i am getting lot of Syntax errors Is there any problems in the way which i followed.If i commented the line #define MANIFEST_RESOURCE_ID 1 MANIFEST_RESOURCE_ID RT_MANIFEST "myproject.exe.manifest" which added in Myproject.h for adding values in .rc file there willnot any error other than this general error c1010070: Failed to load and parse the manifest.
